Some technologically important solid state reactions

In this chapter we shall discuss some solid state reactions which are of technological importance. We shall not be too concerned with providing a quantitative treatment. Technological processes are often much too complex to permit us to give a complete quantitative description of the overall physico-chemical course of the reaction. Instead, we shall apply the previously discussed concepts in two ways. Firstly, we shall attempt to separate out the elementary reaction steps and to describe these steps in terms of fundamental atomic parameters. Secondly, we shall try to describe the processes on the basis of simple limiting cases which can be tested in practice. The examples to be discussed have been chosen somewhat arbitrarily. However, many different areas of solid state chemistry are covered by these examples, and the wide range of applicability of the basic concepts of solid state reactions is well illustrated.

Some technologically important solid state reactions... 

Adsorption is of great technological importance. Thus, some adsorbents are used on a large scale as desiccants, catalysts or catalyst supports others are used for the separation of gases, the purification of liquids, pollution control or for respiratory protection. In addition, adsorption phenomena play a vital role in many solid state reactions and biological mechanisms.
